I've done the controller wrap  - what I think you want, and will push it now.

As to the file names, I didn't want to set up lots of subfolders, partly for tidiness and partly because I didn't know how to code links to files in subfolders using this syntax. I'm open to suggestions.

If you want to have a folder called 'getting_started', we could use the section titles for the file names so there's an indication of content:

````
getting_started/sign_up
getting_started/interface
getting_started/aspects
````

and so on.

If we're going to use URLs of the form `getting_started/file_name`, (a) do I create a subfolder called getting_started in pages, and (b) how do I present links to files contained within getting_started?
